Ed and Oucho's Excellent Inventions - Series 1 - Sir Save-a-Lot

Factual programme. Ed and Oucho travel all over the country making inventions from bits of old rubbish they find in the back of their van. They try to build Sir Save-a-Lot, a robot goalie that's also a karaoke machine. It starts off well, until Oucho realises he doesn't know anything about robots and pretends to be one himself instead. With the Big Big Cheese on their backs, will their general uselessness and lack of science know-how stop them from building the robot in time?
